Do you have a kidney stone? Get on a roller coaster

Certain roller coasters could help eject some of kidney stones or stones (preferably, those that do not exceed 5 millimeters), as revealed by a recent study published in The Journal of the American Osteopathic Association by urologist David Wartinger, a researcher at Michigan State University.

He began the investigation following some anecdotes explained by patients who had managed to dislodge the calculation after climbing into pink mountains of Disney World, specifically the Big Thunder Mountain Railroad.

To carry out this horrific investigation, they could not limit themselves to the experiences of roller coaster users, so that 3D printed an artificial kidney model made of siliconeThey introduced three kidney stones into it and traveled to Disney World to test it. Charging it in a backpack, they boarded numerous times on three roller coasters of this popular theme park.

The only attraction that worked was in the Big Thunder Mountain Railroad; while, on the contrary, the experiment failed in Space Mountain and Rock 'n' Roller Coaster Aerosmith, as Wartinger points out:

In total, we used 174 kidney stones of different shapes, sizes and weights to see what happened.

Therefore, the most effective roller coaster to eject a calculation would be quick, with some twists and turns, but without turning people upside down or making inverted movements. It is also important to occupy the ideal place on the roller coaster: the stones were evacuated in almost 64% of cases when they were sitting in the last row, compared to 16% when they were installed in the front.
